ISO and NRG formats are very different. ISO files are single-track 2048-byte files, while selfbooting Dreamcast discs in NRG format are multisession, multitrack games.
Alex can you please reupload that guide for ripping them on a PC. EDIT: I also got your PM mark, I responded please have a look and get back with me.
thank you very much alex. In that guide he mentions a pack of tools that are needed to use the guide. Are those the tools you posted up earlier for me? or are they something diffrent?
Nope...the tools i posted are used to make a SB image outa a NSB image. For the tools in the Faqs you need to look for yourself, they are easy to find just google for it.;-)
